Grundfos Hydro MPC-E is a compact pressure boosting system with 2 parallel‑connected, frequency‑controlled CRNE 45‑3 multistage centrifugal pumps mounted on a common base frame. All wetted parts are made of stainless steel EN 1.4301 (CRNE). The pumps are equipped with cartridge shaft seals and driven by Grundfos MGE IE5 premium‑efficiency motors (P2 = 18.5 kW, IP54, 3 x 380‑415 V, 50/60 Hz). The unit delivers a rated flow of 108 m³/h and a maximum flow of 140 m³/h with a rated head of 86 m and maximum head of 110 m. The inlet and outlet manifolds are made of stainless steel EN 1.4571/AISI 316 Ti with DN150 connections (PN 16), and include non‑return valves, isolating valves, pressure gauge, pressure transmitter, and a diaphragm tank (18 l). The system is controlled by a Grundfos CU 352 pump controller (IP54) with constant‑pressure PID control, automatic cascade operation, pump changeover, and monitoring functions.
